Medgadget reports on the development by MIT researchers of an implanted cancer fighting patch that uses three elements to tackle tumours.
MIT researchers have created an implantable patch for the administration of three completely different therapies to tumor sites in order to kill and prevent the recurrence of cancer. The hydrogel patch is embedded with gold nanorods that are able to heat up and ablate nearby tissue when illuminated by infrared light. The same rods are also infused with a chemotherapy agent, which is also released when infrared light causes the temperature of the nanorods to rise. In addition to thermal and chemotherapy, the patch also releases RNA gene therapy that targets oncogenes active in the cancer being targeted.
